process_control's Issues

Release a new version for windows-sys 0.42

A commit was merged to increase the version of windows-sys 0.42, but no new version has been released yet. This would be nice to have 🙂

[FEATURE] CPU limit

It would be cool to also limit a proccesses CPU usage similar to https://github.com/aoldershaw/proclimit

Fails to compile - error[E0599]: no method named `si_status` found for struct `siginfo_t`

Hi, @dylni 👋

unfortunately, those boring Starship folks are back again to report some more issues 🙃

This time v3.0.1 failed to compile inside termux/package-builder docker image (https://github.com/termux/termux-packages/blob/master/scripts/Dockerfile) which is used for cross-compiling Termux packages:
https://github.com/termux/termux-packages/runs/1944936544

I believe the environment itself isn't problematic but the way how si_status gets retrieved. Maybe I'm reading this completely wrong and at risk of asking something totally stupid: is it accidentally invoked instead of just being accessed? 🤔
https://github.com/dylni/process_control/blob/3.0.1/src/unix.rs#L171

signal.h manpage says si_status should be declared as an int struct member:

The <signal.h> header shall define the siginfo_t type as a
structure, which shall include at least the following members:

 int           si_signo  Signal number.
 int           si_code   Signal code.
 int           si_errno  If non-zero, an errno value associated with
                         this signal, as described in <errno.h>.
 pid_t         si_pid    Sending process ID.
 uid_t         si_uid    Real user ID of sending process.
 void         *si_addr   Address of faulting instruction.
 int           si_status Exit value or signal.
 long          si_band   Band event for SIGPOLL.
 union sigval  si_value  Signal value.

and compilation ends with following error:

error[E0599]: no method named `si_status` found for struct `siginfo_t` in the current scope

Once again, thank you for all your patience and extensive help in dealing with BSDs, and thank you in advance for all the future help! 💯

Memory Limit Exceeded Support

Name	About	Title	Label
Propose a change that introduces a new functionality that allows detecting when the memory limit of a process has been exceeded and if it exceeds it, killing the process.	Memory Limit Exceeded Support	request

It is very useful when you are going to execute processes in which the established memory limit can be exceeded, for example when you execute a process that runs a programming code of some user, such as a Virtual Programming Judge.

let process = Command::new("echo")
    .arg("hello")
    .stdout(Stdio::piped())
    .spawn()?;

process
    .with_output_timeout(Duration::from_secs(1))
    .memory_limit_exceeded(512MB)
    .terminating()
    .wait()?
    .kill_by_memory_limit_exceeded(|| {
        // Process Memory Limit Exceeded
    })
   .kill_by_timeout(|| {
        // Process timed out
    })?;

error: could not compile `process_control` due to 3 previous errors

which looks at least a bit like it might be related to #4

I realise that this is a Weird Platform, so if you need it I expect I can set up a guest account if that would help with debugging.

openbsd does not have a waitid system call and should use wait4 instead
